Control Options

HP-4 Microprocessor Incorporated in all Mammoth heat pumps. High & low voltage protection. Random start time delay from 5 to 35 seconds. Compressor anti-short cycle protection (5min.) Electronic condensate alarm. Compressor lock out with auto reset. Fan interlock, with compressor operation. Emergency shut down / field supplied signal. Dry contacts for fault indication to DDC control. Aux contacts with compressor operation. Test pin jumper / disables timing circuits for testing. LED fault identification / status indication Removable terminal strip for thermostat wire connections.

Room temperature control HP-4 Microprocessor Room temperature control Can be used with any HEAT PUMP T-stat. Mammoth heat pumps fail to heat (RV) energized for cooling (“O”) terminal. LED unit status codes: “on” steady = Normal operating mode 1 flash = High or low pressure trip. 2 flashes = Emergency shut down (by others) 3 flashes = Auxiliary switch fault. 4 flashes = Condensate alarm 5 flashes = Low voltage fault 6 flashes = High voltage fault 4 tries on auto re-set in 6000 seconds (1.6 hrs) Lock out occurs, and must be re-set manually. (remove call for compressor at t-stat or cycle power to unit)

Mammoth DDC controls I/O Zone 583 Space temperature control 5 digital outputs, 8 universal inputs. 3 analog outputs 100% stand alone control. Capable of communication: via BACnet, Modbus, N2, Lon talk. Includes communication with intelligent space sensors, and keypad/display units. For use with standard CAV heat pumps with water side economizers or hot gas re-heat. Orders must include minimum of one key pad per order.

I/O Zone 583 Typical wiring the same as 560 except 583 has three analog outputs Analog outputs require DC relay for single stage, USC for multi stage or actuator for modulation of control Outputs normally used for re-heat, 3ater side economizers or aux heat Used for CAV with de-humidification and hot gas re-heat. Also special applications with water to water units.

560 & 583 Control Interface Room temperature control RS Plus offers a local setpoint adjustment and override to an occupied mode and LED indication of current status. RS Pro offer the same and a large LCD display. Both sensors provide precision temperature measurement, communication capabilities, able to mate up with key pad for commissioning and maintenance.

Used in large twin, make up air units, primary use for units that have modulation control of heat source or control of VFD,

WSHP Job References

Pacific Bell Park Location: San Francisco, CA A wide range of units were installed throughout the park. They include small horizontal heat pumps, twin circuit verticals, V-Cube Lites, and V-Cubes Mammoth worked with the developer to provide special arrangements and performance that better suited the layout of the park.

Viacom Location: New York, NY Viacom selected V-Cubes and horizontal heat pumps that worked with their open and closed ceilings. Quick delivery was a key point for many units. Some units utilize DDC controls and VAV to service the studio and larger areas of the building.

Quality Living Assisted Care Facility Location: Omaha, Nebraska Quality Living added a new east campus to their facility. The new campus utilized Mammoth high efficiency geothermal heat pumps. The new addition operates more than twice total hours at less cost than the older campus with a conventional boiler and tower system.

Texas Motor Speedway Condominiums Fort Worth, TX Mammoth was awarded the project because of energy savings, noise control, flexibility in right/left hand configuration and meeting the tight closet fit.
